C++ example project scanned on SonarCloud using GitLab CI

This project is analysed on SonarCloud!

It is very easy to analyze a C, C++ and Objective-C project with SonarCloud on GitLab CI:

1. Create a sonar-project.properties file to store your configuration

2. In your .gitlab-ci.yml file:

   1. As the .pre stage:

      1. Download the Sonar Scanner

      2. Download the Build Wrapper

      3. Push both binaries to cache, so they can be used in next step

   2. As part of the build stage:

      1. Install cmake package

      2. Pull Sonar Scanner and Build Wrapper from cache

      3. Wrap your compilation with the Build Wrapper

      4. Push Sonar Scanner and build Wrapper output directory to the cache

   3. As part of the .post stage:

      1. Pull build wrapper output and Sonar Scanner from cache

      2. Run sonar-scanner on the compile_commands.json file inside of the build wrapper output directory

3. Make sure that you have your token stored as a CI variable in your project (SONAR_TOKEN). You can request new tokens using Account/Security page.

You can take a look at the sonar-project.properties and .gitlab-ci.yml to see it in practice.

Linux\CMake

A build of the code repository on a Linux platform using CMake build system.

To build the code run:

mkdir build && cd build
cmake ..
make

Code Description

An example of a flawed C++ code. The code repository can be analyzed automatically, but it can also be compiled with different build systems using different CI pipelines on Linux, macOS, and Windows.

The code repository is forked into other repositories in this collection to add a specific build system, platform, and CI. The downstream repositories are analyzed either with SonarQube or SonarCloud.

You can find examples for:

• Linux

• macOS

• Windows

Using the following build systems:

• CMake

• GNU Autotools

• Xcode

• MSBuild

Running on the following CI services:

• Azure DevOps

• GitHub Actions

• Travis

• Jenkins

• GitLab CI

• BitBucket Pipelines

• Additionally, generic examples demonstrate integration with other CIs and manual-configuration examples should help you if you are running locally.

Configured for analysis on:

• SonarQube

• SonarCloud

You can find also a few examples demonstrating:

• The use of Compilation Database (compile_commands.json)

• Test coverage
